Looks like interaction bounding box is deprecated in the source code, any idea how to go about getting this data ?

Nevermind, I see it :)

The only blocks with interaction boxes (going by the source code) are hopper, cauldron, composter and scaffolding blocks. These can all be done manually if need be. But each block does have its own shape which can be extracted
